Self-drilling screws

Self-drilling screws (also known as Tek screws) are fasteners engineered with a drill-point tip that eliminates the need for pre-drilling pilot holes — saving time and labor on the job site. Designed for direct fastening into metal, wood, and composite materials, self-drilling screws are a go-to choice for contractors, framers, and metal building erectors.

Available in a wide range of point sizes (#1 through #5), drive types, coatings, and lengths to match the material thickness and application requirements. Corrosion-resistant coatings including zinc, ceramic, and stainless options ensure long-term performance in interior and exterior environments.

Common Applications:

• Metal-to-metal fastening (steel framing, HVAC ductwork, metal roofing)
• Wood-to-metal connections (purlins, girts, structural attachments)
• Drywall and sheathing to metal stud framing
• Metal building panel and roofing installation

Common Types:

• Hex Washer Head — high torque drive for structural and roofing applications
• Pan Head & Flat Head — low-profile for interior framing and drywall
• Modified Truss Head — wide bearing surface for thin metal and sheeting
• Pancake Head — flush finish for metal panel applications

Key Features:

• Self-drilling tip eliminates pilot hole requirement
• Available in #1–#5 drill points for varying material gauges
• Zinc, ceramic, and stainless coatings for corrosion resistance
• Meets ASTM and IBC standards for structural applications
